Reading Comprehension activities

1. LET’S START READING
BODY CENTRIC ANTENNA
THE USE OF BODY CENTRIC ANTENNAS TO MONITOR HEALTH CONDITIONS
Electronic systems can use transducers to collect information about changes
in a variety of factors. The systems can then act on the changes observed in a
logical way. If these electronic systems are being used for monitoring the
health or performance of people then often the sensor system needs to be
inside the body to make effective measurements. If the sensor is inside the
body the information may need to be transmitted to outside the body.
This requires an aerial or antenna built into the sensor system in the human.
The antenna has to be able to send a signal to the monitoring device outside
the body. With all the different types of interference that could disrupt the
signal, a radio frequency (RF) device is the best solution available.
Part of these devices will be a low power, two-way radio communication
system via a Body Centric Antenna (BCA). This will let doctors have up-to-
the-minute data from patients. In this way, doctors can adjust treatment
immediately at the point where there are any changes in the patient’s
condition. The BCA allows the patient’s data to be monitored on any
